DESIGN & MANUFACTURING
What to review before selecting a grade
- State the exact alloy and required material condition. A printed alloy and a wrought stock grade should not be substituted on name alone.
- Mark bearing seats, threads, sealing faces and other interfaces that require machining after printing.
- Plan support and powder removal access. Agree on inspection and documentation before releasing a critical application.

Frequently asked questions
What should I include when quoting Stainless Steel 316L?
Send the current CAD, quantity and intended use. Add a drawing for critical fits, the required material condition and any finish or inspection requirements. Confirm availability and the delivered specification in the quotation.
Can I use catalog properties as acceptance criteria?
Use the catalog to shortlist a material. Ask for the exact grade data and agreed test conditions before specifying acceptance limits. Geometry, processing and finishing may affect the delivered part.
Are printed metal parts ready for assembly straight from the machine?
Some applications need secondary machining, heat treatment or surface finishing. Define the delivered condition and critical interfaces in the quotation.
Can I replace a CNC part with a printed version?
Review material equivalence, load paths, surface condition and inspection requirements first. A matching shape alone does not establish equivalent performance.
